Spirit Force
The aETH aToken
Every Aavegotchi is powered by Spirit Force. Upon opening a portal, the summoner (you!) has to imbue your Gotchi with Spirit Force to summon your new-found friend to life!
So what exactly is Spirit Force?
Spirit Force are Aave's interest-bearing tokens embedded within your Aavegotchi! This makes your Aavegotchi increasingly valuable over time!
In Aavegotchi, the terms "Spirit Force", "Collateral", "aTokens", "maTokens", and "amTokens" mean the same thing. Confused? Check out this history page for more information.

Getting aTokens
The following steps are taken from the Zero to Hero Guide 2.0 from Aave Medium. It has been replicated here for the reader's convenience.
1). Head over to the Aave Protocol to get started!
2). Here you have a few options to link your crypto wallet, depending on which type of wallet you have:
3). Before you can use Aave Protocol, you’re going to want to have some crypto assets. The list of available crypto assets are shown in the Stablecoins and the Cryptocurrencies sections above.
If you don’t own any crypto but you want to join the fun, you’ll need to convert your fiat currency (normal money, like dollars, euros, etc.) into a cryptographic asset (like one of the above).
Lucky for you, Aave recently introduced a fiat to crypto onramp where you can buy crypto assets directly from the Aave Protocol application! Now you can use Transak or Ramp Instant to buy the asset of your choice directly with a credit or debit card or wire transfer in just a few minutes (see below).
4). Once you have connected your wallet to the platform, you can deposit an asset into Aave Protocol. When you click “deposit”, the interface will show you what you have available in your wallet to deposit. You then select the asset you would like to deposit, choose how much to deposit, and then voilá, you’ve done it! Note: there will be an "approve" transaction before the actual deposit transaction takes place. This is to grant permission to the deposit contract to use that particular asset you are depositing.
As soon as your deposit transaction goes through, you benefit from the deposit interest rate. The aToken version of the asset can now be seen in your wallet.
Converting aTokens into maTokens
Got your aTokens? Good!
Let's head over to the maTokens page for Step 2!
Differences between maTokens and amTokens
Both maTokens and amTokens accrue interest. However, the way they accrue interest differs:
maTokens increase in value over time. This applies to Haunt 1 Aavegotchis that use maTokens. The value of the maTokens are increasing, but as the quantity does not change, it is not possible to withdraw maTokens from the Gotchis unless you sacrifice your Gotchi to get at the underlying collateral.
amTokens increase in quantity over time. This applies to Aavegotchis from Haunt 2 and onwards. The interest accrued is reflected as quantity. Hence, it is possible to withdraw amTokens once sufficient interest has been generated.
Aura in the Gotchiverse
The larger your Gotchi's Spirit Force, the larger his/her aura in the Gotchiverse.
The calculation for the aura size is as follows:
